NuScale Power, headquartered in Portland, Oregon, made history in 2023 as the first SMR developer to receive design certification from the US Nuclear Regulatory Commission — a process that took over a decade and cost hundreds of millions of dollars. Their VOYGR plant uses factory-built NuScale Power Modules, each generating 77 MWe, stackable in configurations up to 924 MWe. The design relies entirely on passive safety systems — natural convection cools the reactor indefinitely with no operator action or external power required. Despite the regulatory milestone, NuScale's commercial program is currently suspended after their anchor customer UAMPS cancelled their contract in 2023 citing cost escalation. NuScale is now publicly traded on the NYSE (SMR) and is actively pursuing new customers in the US, Romania, and the Gulf region. Backed by Fluor Corporation and the US Department of Energy.
